FRANK C. GREENE, F CLEVELAND, AND CHARLES G. PALMER, OF EAST CLEVELAND, OHIO; SAID PALMER ASSIGNOB TO SAID GREENE.

CONTINUOUS CAR-DUMPING MECHANISM.

To all whom it may concern:

Be it known that we, FRANK C. GREENE and CHARLES Gr. PALMER, both citizens of the United States, residents of Cleveland and East Cleveland, respectively, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Cont-inuous Car-Dumping Mechanism, of which the following is a specification, the principle of the invention being herein explained and the best mode in which we have contemplated applying that principle, so as to distinguish it from other inventions.

Our invention relates to mechanism for handling cars, and particularly to mecha nism for handling of mine cars in the tipples of coal mines. The principle of operation therein exemplified is capable, however, of much wider application, and may be advantageously employed in divers connections where the object sought is the quick and automatic dumping or emptying of material from cars.

To the accomplishment of this object our invention consists of means hereinafter fully described and particularly set forth in the claims.

The annexed drawings and the following description set forth in detail certain 1nech anism embodying the invention, said disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings: Figure 1 represents the tipple of a coal mine, shown in dotted outline, with a form of our improved car-handling mechanism installed therein; Fig. 2 is a side elevation of combined cartransferring and dumping device that forms a feature of such mechanism; Fig. 3 is a front elevation of one of the elements composing such device; Fig. t represents a modification of such car-transferring and dumping device in which it is reduced to its simplest form; Figs. 5 and 6 are detail views of an endless cable that is employed both to move cars to and from the transferring device, and to actuate the latter; Figs. 7, 8, and 9 represent detail views of a device whereby such cable is permitted to pass from the upper to the under side of a track; and Fig. 10 represents in detail the means provided for connecting the car to such cable.

As has been stated, Fig. 1 represents our Specification of Letters Patent.

invention as it appears when installed in the tipple of a coal mine; and, in the particular case illustrated, it is designed to receive the loaded cars at approximately the foot of the tipple structure, elevate such cars to the requisite height within such structure, there dump them, and then return them again to the former level. Such tipple structure is designated by A and, in addition to including the car-handling mechanism about to be described, provides space for railway cars a, or else bins, into which the coal is to be discharged, together with suitable screens and chutes a to separate the coal into its various grades and to properly divert each grade into the receptacle set apart for it. It is to accommodate these screens and chutes and allow space below them for railway cars or bins, that the ordinary tipple is such an elevated structure; and of course the coal from the mine, or in other words the mine cars, require to be introduced and dumped near the top of the structure in order to pass such coal over the screens. The particular method employed to raise the cars to this desired elevation will of course vary with the situation of the mine and tipple. The situation chosen for the purpose of this description is that where the car emerges from the mine at about the level of the foot of the tipple and hence requires to be raised to the top of the same for the reason just explained. Accordingly, leading from a feeding station B, where the cars are received from the mine and to which they are returned on the way back to the mine, we provide upwardly-inclined tracks C C, at the other end of which is the dumping station D. The feeding station E includes two superposed level traclcsections b and b, the lower of which is designed to receive the loaded cars as they come from the mine, the upper of which is designed to return such cars to the mine after they have been emptied. These two tracks may be continued, the one above the other, to the mouth of the mine-shaft, when there happens to be a shaft; where, however, the mine is entered on an incline, both tracks would be brought, of course, to the same level before reaching the entry way of the mine, and merged into one since such entry ways are not usually wide enough to admit of doubletracking. But I omit all the switches and track connections whereby the cars are thus brought to, and conducted from, the tipple, as forming no essential part of the invention here set forth. Continuous with lower track 5 of feeding station B is inclined track C which we shall term the car-delivery track; and continuous with the upper track 6 of such feeding station is the inclined track C which we shall term the car-discharge track. The cars are moved upon the level-track sections 6 b of the feeding station by any suitable means such as endless cables 6 b actuated to move in the proper directions and adapted to periodically engage a car. Movement of the cars up cardelivery track C and down car-discharge track 0 is in the first case effected, in the latter case controlled, by means of another endless cable 0 shown in part in Fig. 1. Such cable 0 is made up of two separate cables or chains 0', one on each side of the car track Figs. 5 and 6. Each of these chains 0 passes around suitably disposed sheaves or sprocket-wheels c at the lower ends of the tracks, and around a single large sprocket-wheel 0* at the upper ends of the tracks, the diameter of such large sprocketwheel 0 being substantially equal to the distance between the two tracks at that point. Cable 0 is driven in the direction indicated by the arrows by a motor a or equivalent means connected with large sprocket-wheels c as shown. The disposition of the sprocket-wheels is such as to cause the chains 0' to lie parallel with tracks C C just without and a little above such tracks. Such chains are preferably made up of solid elongated links 0 pivotally connected at their ends so as to be movable in a vertical plane only. At suitable intervals the adjacent portions of the two chains are connected by means of transverse bars or rods 0 and ,on'

these near their ends are mounted flanged wheels 0 that are adapted to travel on supplementary rails C running alongside the rails of each of tracks C and C.

The transverse bars a, by being mounted upon wheels in the manner just described, serve to support the chains and are further adapted to be utilized to engage the cars to move them up the car-delivery track and to hold them in check .in coming down the cardischarge track. To effect such engagement each car K is provided, Figs. 5 and 10, with a catch consisting of an angle iron is or similar means secured transversely across its bottom and projecting downwardly far enough to be engaged by a bar 0 as the cables carry such bar along.

In order that cable 0, by which term it is seen we designate the structure formed of the two parallel chains and the cross-bars connecting the same, may pass freely from the upper to the under side of car-discharge track C at its lower end, the arrangement illustrated in Figs, 7, 8, and 9 is provided.

At the point where such passage is to be effected a similar short section 0 of each rail of the track is mounted atits lower forward permitted to glide through the break thus made in track C, which closes, however, immediately thereafter, as arms 0 drop into place again. To insure such closure of the track itis advisable to provide more positive means than mere force of gravity. To this end, the arms 0 are extended forwardly and downwardly to form other arms 0 These are so positioned as to engage wheels 0 of the cable as the latter moves on beneath the track, the effect of such engagement being the raising of the arms and the forcing of the track-section c" into place. The ends of track sections 0 it will be further noted, are raised just high enough to engage the wheels of the passing car, thus obviating the use of any independently operated stop to retain the car pending the closing of such track-section.

Dumping of the loaded car, which is moved up car-delivery track C by means of cable 0 in the manner just set forth, "is effected atthe dumping station D at the upper end of such track; and, simultaneously with the dumping operation, the car is transferred from the lower car-delivery track to the upper car-discharge track preparatory to its return to the feeding station 13, and thence to the mine. The mechanism by which such dumping and simultaneous transfer of a car is accomplished is illustrated in its simplest form in Fig. 41-, while Figs. 2 and 3 show the same elaborated into a structure that, while not essentially departing therefrom in principle of operation, is adapted to operate much more rapidly. The simple form of device thus illustrated in Fig. l, it should be stated, is specifically claimed in a separate application filed September 6, 1907, Serial No. 391,565.

Considering the device first as shown in Fig. 4;, it is seen to comprise a frame D pivotally mounted on an axis transversely disposed relatively to tracks G and G. A counterweight D is provided in connection with such frame, but should not suffice to overbalance it; accordingly it 'will normally occupy the position indicated in full lines in aforesaid figure, being retained in such position by a stop (Z. As shown, the frame in such normal position is inclined at an angle of about 60 from the horizontal; the exact degree of inclination, however, being immaterial so long as it is sufiicient to cause a car when similarly inclined to readily discharge its contents. hen in such normal position, the lower free end of frame D is designed to register with the upper end of car-delivery track C which is curved upwardly to meet it, thus avoiding a sharp turn in the track. The portion cl of frame D that registers thus with the end of track 0' is provided with rails or equivalent means adapted to form a continuation of the rails of such track so that a car may pass readily off the track and onto the frame.

The same endless cable 0 that is utilized to move the cars along track C, serves also to urge them off onto the inclined trackporticn cl of frame D. To this end the large sheaves 0 about which the cable passes are located substantially as indicated in Fig. 4 with reference to the upper curved end of track C and the lower portion of frame D whereby the cable is maintained practically parallel with both. In addition to the track-portion d, frame D is provided with arms (Z one on each side of such track and parallel therewith. These arms have a track surface on their under sides and are so disposed laterally as to present such track surface just above the wheels 0 that have been described as being mounted on the outer ends of the bars whereby the two chains formingcable c are connected. Thus, as a pair of the wheels are borne along by the cable they are brought into engagement with such arms 6 the effect of such engagementas the cable begins toascend in passing around sheaves. 0 it is readily seen, is to carry the whole frame upward, with the car previously deposited thereon, until it rests in the position indicated in dotted outline in the figure just referred to. In this position the free end of the frame registers with the upper end of car-discharge track C and as the cable passes across the upper side of sheave 0* and thence along the track it disengages such wheels 0 from arms CF, and leaves the frame free to swing back again to its normal position. Means are provided, however, whereby the frame is retained in register with track C long enough to allow the car borne by the former to pass off onto the latter; such means comprise a latch d positioned by means of a weighted arm (Z to automatically engage the end of the frame as it swings upwardly. As the car, after leaving the frame, passes along track C, it, or rather the cross-bar 0 joining the chains, which immediately precedes it, engages a trip-arm (i properly connected with latch (Z by a bar (Z to thereupon swing the latter out of engagement with the frame. The

return of the frame to the lower position in which it rests against stop cl is of course controlled by the counterweight previously described.

The dumping of the car is effected incidentally to its transfer from track C to track C by simply opening its end-gate k which is preferably hinged in the manner shown in Fig. 5. Such opening of endgate is and consequent dumping of the car may be effected manually, or automatically by mechanical means which do not appear in this specification or form a part of my present invention; it should occur, however, a little before the car reaches the oscillatory frame D and before such frame has been engaged by the cable 0 in order that the car may be entirely emptied before being raised to the upper level. The number and disposition of bars a, connecting chains 0, should be such as to permit cars to successively arrive at the upper end of car-delivery track C just a little after the frame D resumes its normal position.

It will be observed that a short interval of time is lost pending each resumption by frame D of this normal position and the frequency with which cars can be fed upon the car-delivery track is thus limited. In order, therefore, to make possible a greater rapidity of operation we have devised the form of transferring device illustrated in Figs. 2 and 3. As will be readily apparent upon an inspection of these figures, and of Fig. 1, in conjunction therewith, this preferred form of transferring device comprises essentially a plurality of frames E each equivalent to the previously described frame D in every way, except that the track-portion 6 designed to register with tracks C and C is shown as the member supported by the frame proper, while the lower portion 6 of the frame itself is utilized to form the cable-engaging member, in eontradistinction to the construction of frame D where the opposite arrangement of these parts obtains. Such frames E are suitably attached to a large hub E mounted upon an axis E that occupies a position with reference to the ends of tracks C and C similar to that occupied by the pivotal aXis of frame D. The frames E accordingly radiate like spokes from the hub E and their number is such and they are so spaced that when one such radial frame registers with car-discharge track C, the one following it will register with car-delivery track C. As cable 0 in the course of its travel brings a bar 0 with wheels 0 thereon into engagement with member 6 of the frame that happens to register with the cardelivery track, such frame will be raised into position to register with the car-discharge track, and the succeeding frame will be brought around opposite to the car-delivery track. Thus it is evident that the entire device will be gradually rotated on its aXis, each passage of a cross-bar 0 along the dumping station effecting its rotation through the angular distance between two successive frames. The wheel is prevented from rotating in a reverse direction by means of a latch c Fig. 1, pivoted so as to lie in the path of the outer ends of the frames E and adapted to permit their movement in the desired direction only.

From the construction of the form of our transferring device just described it is seen that there is no reversal in the movement of such device and hence no delay attendant upon its return to the operative position as is the case in the simpler form first described. In fact it is capable of handling cars just twice as rapidly as is the other. While the operation of this important feature of our invention has been, perhaps, clearly enough indicated in connection with the description given of the two forms of its construction, it may be well to describe the operation of the car-handling mechanism as a whole. The cars upon their arrival from the mine are run onto track I) of the feeding station from which they are fed one by one upon car-delivery track C. The object of such feeding station is to insure the proper timing of the arrival of cars upon track 0, since it is evident that were a car to be brought to the foot of such track just as a cross-bar of cable 0 was descending, the consequences would be disastrous to the mechanism of the plant. Accordii'igly feed ing-cable 6 in addition to being connected to operate in unison with cable 0, should be an aliquot part of such cable, its length being equal, in fact, to the distance between successive bars in cable 0. From this arrangement it is evident that a car placed upon track 6 of the feeding station will not be moved off the same until the cable 0 is in proper position to receive it. The car, once it is on track C, is engaged by a crossbar 0' of cable 6 and thereby carried up the inclined portion of the track; upon its arrival at the tracks upper end, it is pushed upon the more sharply inclined track-section of frame D or E, according as to which type of transferring device is being employed. Just previous to its arrival on such frame, however, the end-gate of the car is raised and its load discharged, while by the time that it is wholly on the frame, the engagement of the wheels 0 on the par ticular cross-bar c that has moved the car, with arms (Z or 6 swings the aforesaid frame upwardly and into register with the upper car-discharge track C. Along this track the cable 0, having passed around sheaves c of course runs in the opposite direction. Wheels 0 are accordingly withdrawn from beneath the arms of the frame and such frame and track being still on an incline, the car follows and moves down the track as fast as the cable will allow it. At the lower end of track 0 the cable passes below the same and around lower sheaves 0 0 the cross-bars being allowed to pass beneath the track by means of the device shown in Figs. 7, 8 and 9.

Where just a single vibratory frame D is employed at the dumping station, cross-bars 0 must be spaced sufliciently far apart to allow the frame to swing back into its normal position before the arrival of a second car. When, however, a series of radially mounted frames E is used, a second frame is in position to receive the following car as soon as the first frame with the first car is in register with the discharge track, as will be readily understood. In either case it is seen that the cable by means of such cross-bars serves to move the cars to the upper end of the car-delivery track, there place them upon the transferring frame, and while retaining them thereon, swing such frame upwardly into alinement with the car-discharge track. On the car-discharge track the same cable serves to hold the cars in check, finally allowing them to run off onto the upper track of the feeding station.

The various advantageous features of our system of handling and dumping cars have been sufiiciently indicated in passing. It should be pointed out, however, that considerable modification can be made of such system, and especially of the car-delivery and car-discharge tracks, without departing from the spirit of the invention. Such sug gested modification might in fact be required to adapt our system for use in other situations than the one here chosen for illustration, where the mine happened to be differently situated with reference to the tipple.
